Fast Soft Recovery

Rectifier Diode, 20 A

20ETF..S Soft Recovery Series

Vishay High Power Products

FEATURES/DESCRIPTION

The 20ETF..S fast soft recovery rectifier series has been

optimized for combined short reverse recovery time and low

forward voltage drop.

The glass passivation ensures stable reliable operation in

the most severe temperature and power cycling conditions.

This product series has been designed and qualified for

industrial level.

APPLICATIONS

• Output

rectification

and

freewheeling

in

inverters,

choppers and converters

• Input rectifications where severe restrictions on conducted

EMI should be met
